腾讯云的官方文档很多人都看不懂，demo也写的没什么借鉴性？而且还是MRC的，一开始我也抱怨好久，找了半天才弄好，分享出来主要代码

导入头文件

#import #import

添加属性

@property (nonatomic, assign)TX_Enum_PlayType playType;
@property (nonatomic, strong)TXLivePush * txLivePublisher;
@property (nonatomic, strong) UIView * backView;
@property (nonatomic, strong) UIView * placeholderView;
@property (nonatomic, strong) UIButton * PlayBtn;
@property (nonatomic, assign) NSInteger  placeholderHeight;
@property (nonatomic, strong) TXLivePlayer * txLivePlayer;

主要代码

- (void)viewDidLoad {
    [super viewDidLoad];

    self.view.backgroundColor = [UIColor whiteColor];
    
    //将原点移动到navigationBar
    self.edgesForExtendedLayout = UIRectEdgeNone;
    
    self.navigationController.navigationBar.barTintColor = [UIColor redColor];
    
    // 16 : 9
    _placeholderHeight = selfWidth / 16 * 9;
    
    //设置占位背景
    self.placeholderView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, selfWidth ,_placeholderHeight)];
    
    _placeholderView.backgroundColor = [UIColor blackColor];
    
    [self.view addSubview:self.placeholderView];
    
    self.backView = [[UIView alloc]initWithFrame:CGRectMake(0, _placeholderHeight, selfWidth, 35)];
    
    [self.view addSubview:_backView];
    
    self.hengPingBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    
    _hengPingBtn.frame = CGRectMake(selfWidth - 40 , _placeholderHeight - 40, 40, 40);
    
    [_hengPingBtn setImage:[UIImage imageNamed:@"fullscreen_icon"] forState:(UIControlStateNormal)];
    
    _hengPingBtn.selected = YES;
    
    [_hengPingBtn addTarget:self action:@selector(hengPingButtonAction:) forControlEvents:UIControlEventTouchUpInside];
    
    [self.placeholderView addSubview:self.hengPingBtn];
    
    
    //    PlayBtn
    self.PlayBtn = [UIButton buttonWithType:UIButtonTypeCustom];
  
    _PlayBtn.frame = CGRectMake(0 , _placeholderHeight - 40, 40, 40);

    [_PlayBtn setImage:[UIImage imageNamed:@"stop_icon"] forState:(UIControlStateNormal)];
    
    _PlayBtn.selected = YES;
   
    [_PlayBtn addTarget:self action:@selector(PlayBtnAction:) forControlEvents:UIControlEventTouchUpInside];
    
    [self.placeholderView addSubview:self.PlayBtn];
    
    
   _txLivePlayer = [[TXLivePlayer alloc] init];
    
    [_txLivePlayer setupVideoWidget:CGRectMake(0, 0, 0, 0) containView:self.placeholderView insertIndex:0];
    
    _txLivePlayer.enableHWAcceleration = YES;
    
    TXLivePlayConfig  *_config = [[TXLivePlayConfig alloc] init];
    
    //流畅模式
    _config.bAutoAdjustCacheTime   = NO;
    // 播放器缓存时间
    _config.cacheTime  = 3;
    
    [_txLivePlayer setConfig:_config];
    // 全屏
    [_txLivePlayer setRenderMode:RENDER_MODE_FILL_SCREEN];
    
     [_txLivePlayer setRenderRotation:HOME_ORIENTATION_DOWN];
    
    //  播放                  播放地址
    [_txLivePlayer startPlay:@"rtmp://live.hkstv.hk.lxdns.com/live/hks" type:_playType];
}

解释下代码

腾讯云的播放器，是不能直接调整帧

要修改控件的大小和位置，请调整父视图的大小和位置

通过调整占位符的帧来修改播放器帧

//全屏图像铺满屏幕

 [_txLivePlayer setRenderMode:RENDER_MODE_FILL_SCREEN];

//家在下面

[_txLivePlayer setRenderRotation:HOME_ORIENTATION_DOWN];

// _playTyp代表支持的所有格式：

RTMP直播，FLV直播，FLV点播，HLS点播，MP4点播

[_txLivePlayer startPlay:@"rtmp://live.hkstv.hk.lxdns.com/live/hks" type:_playType];

点击事件和是否横屏判断

#pragma mark  ====   全屏点击事件
- (void)hengPingButtonAction:(UIButton *)sender{

    if (sender.selected == YES){

        [self.view bringSubviewToFront:self.placeholderView];

        [Tools orientationToPortrait:UIInterfaceOrientationLandscapeRight];

        self.placeholderView.frame = [UIScreen mainScreen].bounds;

        _hengPingBtn.frame = CGRectMake(selfWidth - 40 , selfHeigh - 40, 40, 40);

        [_hengPingBtn setImage:[UIImage imageNamed:@"exitfullscreen_icon"] forState:(UIControlStateNormal)];

        [_PlayBtn setFrame:CGRectMake(0, selfHeigh - 40 , 40, 40)];

        self.navigationController.navigationBarHidden = YES;

        sender.selected = NO;

    } else {

        [Tools orientationToPortrait:UIInterfaceOrientationPortrait];

        [_hengPingBtn setImage:[UIImage imageNamed:@"fullscreen_icon"] forState:(UIControlStateNormal)];

        self.placeholderView.frame = CGRectMake(0, 0, selfWidth  , _placeholderHeight);

        _hengPingBtn.frame = CGRectMake(selfWidth - 40 , _placeholderHeight - 40, 40, 40);

        [_PlayBtn setFrame:CGRectMake(0, _placeholderHeight - 40, 40, 40)];

        self.navigationController.navigationBarHidden = NO;

        sender.selected = YES;

    }

}

#pragma mark  ====  播放  暂停  事件
- (void)PlayBtnAction:(UIButton  *)btn{
    if (btn.selected == YES){
         [btn setImage:[UIImage imageNamed:@"play_icon"] forState:(UIControlStateNormal)];
        // 暂停
        [_txLivePlayer pause];

        btn.selected = NO;
    } else {
        [btn setImage:[UIImage imageNamed:@"stop_icon"] forState:(UIControlStateNormal)];
        // 恢复
        [_txLivePlayer resume];

        btn.selected = YES;
    }
}

- (void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];

    AppDelegate * delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;

    delegate.allowRotate = 1;
}

- (void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];

    AppDelegate * delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
    delegate.allowRotate = 0;

}

工具类里的转屏

//强制旋转屏幕
+ (void)orientationToPortrait:(UIInterfaceOrientation)orientation{

    SEL selector = NSSelectorFromString(@"setOrientation:");

    NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];

    [invocation setSelector:selector];

    [invocation setTarget:[UIDevice currentDevice]];

    int val = orientation;

    [invocation setArgument:&val atIndex:2];//前两个参数已被target和selector占用

    [invocation invoke];
}
